HELP!!!! AGAIN AND AGAIN!!!!

[Fontvregal]

We don't understand this errors:

C:\Users\RED1\projects\MiProyecto\Debug\main.o: In function `main':

C:/Users/RED1/projects/MiProyecto/main.cpp:10: undefined reference to `modulodeprueba()'

C:/Users/RED1/projects/MiProyecto/main.cpp:11: undefined reference to `mostrartriangulo()'

collect2.exe: error: ld returned 1 exit status

Can you explain them to us?

  #include<iostream>
using namespace std;

void tartaglia();
void modulodeprueba();
int factorial();
void mostrartriangulo();

int main () {
	modulodeprueba();
	mostrartriangulo();
	return 0;
}
const int N=29;
typedef int TMatriz [N][N];
void tartaglia (TMatriz A){
	int i;
	int j;
	for (j=0; j<=N; j++){
		for (i=0; i<=j; i++){
			if ((i=0) || (i==j)){
				A[i][j]=1;
			}
			else{
				A[i][j]=A[i][j-1]+A[i-1][j-1];
			}
		}
	}
}
void modulodeprueba(TMatriz A){
	int n;
	int m;
	int factorial(int x);
	n=8; 
	m=0;
    cout<<"El número es "<<factorial(n)/(factorial(m)*factorial(m-n))<<" y en la matriz está "<<A[n][m]<<endl;
	n=3; 
	m=3;
    cout<<"El número es "<<factorial(n)/(factorial(m)*factorial(m-n))<<" y en la matriz está "<<A[n][m]<<endl;
	n=2;
	m=1;
	cout<<"El número es "<<factorial(n)/(factorial(m)*factorial(m-n))<<" y en la matriz está "<<A[n][m]<<endl;
	n=5; 
	m=2;
	cout<<"El número es "<<factorial(n)/(factorial(m)*factorial(m-n))<<" y en la matriz está "<<A[n][m]<<endl;
}
int factorial (int n) {
	if (n==0)
		return 1;
	else 
		return n * factorial(n-1); 
}
void mostrartriangulo(TMatriz A){
	int M;
	cin>>M;
	int i;
	int j;
	for (j=0; j<=M; j++){
		for (i=0; i<=j; i++){
			cout<<A[i][j]<<" ";
		}
		cout<<endl;
	}
}

you declare:
void modulodeprueba();

but you're signature for that function when you come to implement it is:
void modulodeprueba(TMatriz A){

They need to match or else the compiler wont be happy.
Change line 5 to
void modulodeprueba(TMatriz A);

and the same for the other function it's moaning about as well.

[Fontvregal]

It's still failing, can you give us another solution?

[mutexe]

that IS the 'solution'.
What are the errors now? Post updated code please.

[Fontvregal]

Same errors, it's probably my program, thanks for all.

[mutexe]

I don't believe you :)
Did you change the function declarations like I advised in my first post?

edit:
this line:
typedef int TMatriz [N][N];

needs to go near the top. before your function declarations.

edit 2:
But first, seriously, I'd read this:
http://www.cplusplus.com/doc/tutorial/functions/

You need to make sure your declarations and impl signatures match AND call them passing in what the function expects. On your line 10 you write:
modulodeprueba();

but you need to pass in an object of type 'TMatriz' as this is what you've specified in your function implementation.
